Changing background art style in the menu screens

Would it be too difficult to change the art style of the game? I mean in the menu and that,

I mean to say in the Wizard101 menu screens, maps, buttons such as the play button+, And even the website, the art is a whole lot more detailed then the Pirate101 menu art.

The pirate101 background art in the game menu, website, in game backpack does not have any detail and looks as though the people making the art for the backgrounds for these things in Pirate101 were, would I say lazy compared to the people who did the Wizard101 backgrounds for these things.

I do not want to sound rude when I ask if we could change the detail in this,
